Gas chromatographic studies of the relative retention of the sulfur isotopes in carbonyl sulfide, carbon disulfide, and sulfur dioxide

Creators

Description

A precision gas chromatograph, coupled to a quadrupole mass spectrometer and an on-line computer, was used to study the fractionation on Porasil A of the 32S/34S isotopic pair in a variety of sulfur-containing molecules. Carbonyl sulfide (COS) yielded an average α value of 1.00074 +- 0.00017 (standard deviation) for the temperature range 250C to 750C. The carbon disulfide (CS2) value was 1.00069 +- 0.00023 for the range 530C to 1030C, and that for sulfur dioxide (SO2) was 1.00090 +- 0.00018 for the range 620C to 1120C. Differential thermodynamic data have been reported. A Porapak Q column showed no fractionation of this isotopic pair in these three molecules
